Features
The ultimate in compactness and operational capability
Geared toward the smallest depth in the world
Direct connection of the isolating main contacts to the hinges of the fixed main contacts
eliminates the need for intermediate conductors. Allowing the DH series ACBs have the
world’s smallest depth resulting in space saving in switchboards.
DH Series
DB series
More than twenty design patents have been registered for the DH series ACB.
Saved Space
The height and depth dimensions are identical in all sizes to 3200A. There are two common
widths or frame size, from 800-2000A and from 2500-3200A for the standard series. The
panel cutout size is the same for all types of DH series ACB, which makes it easy to arrange
the ACBs in switchboards.
Maximum power from minimum volume was central to the design specification. With a depth
of 290mm for the fixed type and 345mm for draw-out, it is one of the smallest ACBs in the
world.
ACBs with front connections are available off-the-shelf.
Front connections are especially suitable for smaller-depth switchboards

Increased accessibility from the front
It enhances ease of installation, operation, and maintenance.
The double insulated design ensures that most accessories can be safely and easily,
installed by the user. Control, auxiliary and position switch terminals are mounted at the
front on the ACB body for easy access. Due to the increased level of harmonics within the
distribution network, the neutral phase is fully rated as standard.
Connection to the
control circuit
Replacement of
internal parts
(Removing the front cover
enables replacement of
internal parts.)
No extra arc space required,
vertical stacking permitted
The DH series ACB dissipates all arc energy
within its unique “Double Break” arc chamber.
The internal energy dissipation within the ACB
allows the clearance distance of the ACB to
nearby earthed metal to be zero. This will assist
in minimizing switchboard height and costs.

A high performance and reliability
Very fast interruption by
“Double Break” system
The unique “Double Break” main contact system ensures
extremely fast interruption of short circuit currents and substantially
reduces main contact wear. The internally symmetrical
“Double Break” structure allows reverse power connection.
No clamp screws used for the main circuit
contact units
Isolating main contact
There are no clamp screws or flexible leads in the main circuit
contact units.
This substantially enhances the durability of the main circuit contact
units and improves the reliability in ON-OFF operation.
Fixed main contact
Moving main contact

Enhanced selectivity
L Long time delay
S Short time delay
I Instantaneous
At Fuji we are so concerned about selectivity that all our
protection relays have ‘LSI’ characteristics as standard.
This provides an adjustable time delay on overload (L) and also the
l2t ramp characteristic (S).
As shown, these are essential to provide selectivity when grading
with other protective devices such as downstream fuses and
upstream relays.
The standard ‘LSI’ curve provides more than five million
combinations of unique time current characteristics.
Zone selective interlocking is available to provide zero time delay
selectivity.
As the rated breaking capacity is identical to the rated short-time
withstand current full selectivity can be achieved.

FUJI ACB provides positive protection for
electric power systems.
The Fuji ACB DH series is equipped with an RMS sensing over-current
release (OCR) having a wide range of protection functions and capabilities.
Optimum protective
coordination
Inverse Definite Minimum Time (I.D.M.T.)
Why use a separate panel mounted protection
relay when you can have all the benefits of
I.D.M.T. protection integral to the ACB?
Fuji ACB is available with a choice of flexible
protection curves to assist in selectivity
applications.
S.I. Standard Inverse
V.I. Very Inverse
E.I. Extremely Inverse
All these curves are user definable and comply
with IEC 60255-3. Standard transformer and
generator protection characteristics are also
available.

AGR-L Industrial & transformer protection
AGR-S Generator protection
AGR-R Characteristics to IEC 60255-3
Overload protection
Adjustable from 40–100% of rated current.
True r.m.s detection up to the 19th harmonic, a
distant vision for the competition who rarely
see past the 7th. Neutral protection for all
those Triple-N harmonics, such as 3rd, 9th and
15th. Also in case we forgot to mention, a
“thermal memory” as standard!
Two channel pre-trip alarm function
(S-characteristic) ✽1
This function can be used to monitor and
switch on additional power backup to feed
critical circuits. For example, the function can
be set so that when a pre-trip alarm is
activated, an emergency generator starts to
ensure a constant supply. This feature is only
available on some AGR21 OCR models with a
generator “S” characteristic.
N-phase protection function (optional)
In 3-phase, 4-wire systems that contain
harmonic distortion, the 3rd harmonic may
cause large currents to flow through the
neutral conductor. The N-phase protection
function prevents the neutral conductor from
sustaining damage or burnout due to these
large currents. Available in all OCRs except for
generator “S” characteristic types.
Standard OCR with adjustment Enhanced OCR with adjustment
dial Type AGR-11.
dial Type AGR-21.
Reverse power trip function
(S-characteristic) ✽1
(The first-ever feature for ACBs)
This feature provides additional protection
when paralleling generators. The AGR21 OCR
for generator protection with the reverse power
trip function, negates the need for installation
and wiring in an external reverse power relay.
This feature is available using an AGR21 OCR
with a generator “S” type characteristic only.
Earth leakage trip function
(L/R-characteristic) ✽1
Used in conjunction with an externally
mounted Zero phase Current Transformer
(ZCT), this function provides protection against
leakage to earth of very small levels of current.
Trip or alarm indication, and contact output is
available to enhance the level of system
protection. Available using general purpose L /
R -characteristic AGR21 OCR.
Adjustable undervoltage
trip function UVT ✽1
Available as a fixed type, or with adjustable
voltage pick up and an adjustable time delay. 3
Phase, Phase failure protection is also
available. AGR11/21 OCR's.
08
Contact temperature
monitoring function (optional) ✽2
This function monitors the temperature of the
ACBs main contacts. An alarm indicates when
the temperature exceeds 155°C. Continuous
monitoring of the contact temperature provides
valuable input for preventative and predictive
maintenance programs.
✽1: Not available for standard OCRs, type AGR-11.
✽2: Available for type AGR-21 OCR only.
